Our range of package unit air conditioners A variety of sizes and capacities to effectively heat and cool large and small spaces.When you choose one of our package units, you can also take advantage of the following: Why hire a package unit? These stand-alone units offer a near unbeatable temperature control solution, especially when floor space is at a premium. Package units can also be used for events, emergency response situations, and other temporary or urgent scenarios. Package units house all of their components in a single outdoor unit that sits on the side of a building or on the roof.

These systems are designed specifically for homes, offices, hotels, and other spaces that have limited floor space and don’t have a furnace and coil or air handler. More often than not, sheet metal is the safest and most effective material for creating ductwork.A package unit – sometimes referred to as a package unit air conditioner – is a streamlined all-in-one heating and cooling system. When installing an air conditioning system, consult with your contractor to find out which type of duct is best for your home or office. Also, because the surface is rough, they can also affect airflow and efficiency. However, it’s not recommended for ventilation because, like fiberglass-lined ducts, they can become a breeding ground for mold and mildew in humid climates.

This type of duct is good for cooling and heating systems because it is well insulated by itself. These ducts can also become contaminated with molds and bacteria.įiberboard is made from fiberglass strands that have been compressed and bonded with a resin, and then covered with a sheet of foil laminate to protect them from moisture. Fiberglass-lined ducts are also difficult to clean for this same reason: the cleaning process can damage the lining and release fibers. However, the fiberglass in these ducts can deteriorate and eventually release fiberglass particles into the air – this is a major health concern, especially with long-term exposure. This type of duct is common in office and commercial buildings, as it dampens the sound of the air conditioner unit. These are sheet metal ducts (like those described above) that have internal or external fiberglass lining. They are also the least likely to harbor dangerous molds or growths because they have non-porous surfaces. Aluminum in particular is relatively light and easy to install. These are the kinds of ducts you’ve seen in films – usually with an action hero crawling through them! Galvanized steel and aluminum are the most common materials for sheet metal ducts. The most common types of rigid ductwork are: They come in a variety of materials and sizes, and can be either cylindrical or rectangular. You can find out more about flexible ducts and their installation guidelines from the American Society of Home Inspectors. The advantages of flexible ducts are that they are fairly quick and easy to install, and often cost less than rigid ductwork.

Kinks, bends, and turns also need to be minimized – these reduce air flow and could hamper the efficiency and effectiveness of the air conditioner. For example, flexible ductwork needs to be secured and supported properly, ensuring little sagging or snaking. Like most central air conditioning parts, flexible ducts have specific installation requirements. This kind of ducting is best in tricky spaces where rigid ducts are just not possible to install, or used to attach non-flexible ductwork to an air supply outlet. Flexible Ductworkįlexible ducts are typically tube-shaped, made of a wire coil covered with a bendable, durable plastic, and surrounded by insulation. Let’s look at some of the different types of ducts needed for air conditioning. Ducts for central air conditioning can also be used for heating and filtering systems. We’ve had a look at the different compressors and condensers used for central air conditioning, but what about the ducts? Simply put, a duct is the channel that carries cooled air from the air conditioning unit through your home, and can also remove warm or stale air.
